ELECTRIC SIGNALING DEVICE.

Patented June 4, 1907.

Application filed September 1,1906. Serial No., 383,003.

To all whom it may concern:

Be it known that I, EDWARD L. ORCUTT, a citizen of the United States, and a resident of the borough of Manhattan, in the county, city, and State of New York, have invented certain new and useful Improvements in Electric Signaling Devices for Railways, of which the following isa specification.

This invention relates to electric signaling systems for railways; I

It seeks to provide an efficient, economical and reliable system and also one in which both track signals and cab or train signals may be utilized. The track signals are arranged in blocks along the track.

The invention also seeks to provide an efficient, reliable and economical arrangementby means of which the brakes may be a plied to stop the train when the block about to be entered is dangerous or occupied by a preceding train. I

In the accompanying drawings forming part of this specification, and in which like numerals indicate corresponding parts in the several figures, Figure 1 1s a diagram embodying the invention and showm a mto blocks of which rails 1 and 3 single track signal for the block; Fig. 2 1s a similar view showing a plurality of track signals for a block and associated mean's on the train for stopping the train; and Fig. 3 is a diagrammatic representation of a rotary transformer or motor dynamo which may be used in place of the stationary transformer shown in Figs. 1 and 2.

Referring now to the dra and more particularly to F g. 1, the trac is divided belong to the second block, and rails 1 and 4 belong to the third block. Rails 2, 3, 4, etc. are insulated from each other. Rail 1 may, as shown, be electrically continuous through the several blocks. 5 and 6 are two separate track contacts associated with the block to which the rails l and 3 belong. These track contacts 5 and 6 consist of suitable electric conductors which extend along the track for a suitable distance immediately in advance of the block to which they belong. They are preferably formed of rails fixed on the road-bed. Track contact 5is connected by wire 7 to 'rail 3 at the entering end of the block. At the'opposite end of the block is transformer 8 whose secondary coil 9 is connected bywire 12 to rail 3.and by wires 10'.

and 11 to rail 1. Primary coil 13 of transformer 8 is connected by wire 15 to wire 11" This track a danger and sa ety indication, as required, and this signal may be operated from any convenient source, but preferably from a source of electricity located on the train. As shown in the drawings, this signal consists of two lamps. One lamp lights up to show that the guarded block is dangerous,

as for example when a train is occupying this block. The other lamp lights up to show that the guardedvblock is safe, as for example when there is no train in this block. As

shown in the accompanying drawings, the

signal consists of these danger and safety lamps and is operated from the supply circuit for the transformer said supply circuit including the track contact 6, wire 14, primary coil of transformer 8, and'rail 1. Armature of magnet 17 is connected by wire 19 to wire 14. Back contact 21 is connected by wires 22 and 24 to wire 25 and includes lamp 23. Front contact 27 is connected by wires 28 and 30 to wire 25 and includes lamp 29. Wire 25 is connected to wire 18. Thus lamps 23'and 29 are arranged to be connected alternately in a shunt or bridge across the supply circuit. When magnet- 17 is denergized and armature 20 is retracted by its spring 26, the shunt is closed through lamp 23. When, however, magnet 17is energized, the armature 20'moves over to contact 27, lamp 29 is included in the shunt 23 is cut out. In the preferred arrangement'of the system ,the generator for the supply circuit is carried on the train. Any suitable type of generator may be employed. 31 is the generator on the train. One side of this generaand lamp tor is connected by wires 32 and 52 to a travel- I ingcontact 51, carried by the train. This' travelin contact,=as the train advances, is

arrange to make connection with track contact 6. The opposite side of' the generator is connected by wires 38 and 54 to a traveling tor 31.

I includes lamp 48.

- cludes lamp 43.

- energizing magnet 17. 43 and 48'indicate electric lamps carried in the train, and preferably in the engine cab, and constitute a.

train signal. This signal is controlled by magnet 36 carried in the train, the arrangement being such that when the magnet is energized the lamp 43 will be lighted to indicate'safety, and when this ma net is den-- ergized the lamp 48 will be lig ted to indi-' cate danger. 'Magnet 36 is connected on one side by wire to traveling contact 34 carried on the train, and is connected 'on its other side bywires 37 and 54 to travelin contact 53. raveling contact 34 is arranged to make electric connection with a track contact 5. When the train reaches track contact 5, magnet 36 is connected in the track circuit as follows-from magnet 36 through wire 35, traveling contact 34, track contact 5, wire 7, rail 3 secondary coil 9 of transformer 8, rail 1, traveling contact 53, and wires 54 and 37 to magnet 36. If, at this time, the" primary coil of the transformer is energizedand there is no train "in the block, magnet 36 will be energized and will cause If, however,

the safety lamp 43 to lig t u I and a train is primary coil 13 is energize occupying the block, and thereby shunting the current in the track circuit, magnet 36 will be deenergized and danger lamp 48 will light up. The circuit for these lamps will be presently explained. is the armature of magnet 36 and is connected by wire 39 to one side of the generator 31. Back contact 47 is connected byv wires 49 and to Wire 46 and nected by wires 44 and 45 to wire 46 and in- Wire 46 is connected by wires 37 and 38 to the opposite side of the generator 3 1.

- ture 40 on the back contact 47 when magnet 36 is not energized. The generator is designed to be continuously active so as to light up either lamp 43 or 48de ending upon the condition of magnet 36. ire 32 is connected to back stop 33 of the traveling contact 34. This traveling contact 34, when it.

makes connection with the stationary con,- tact 5, opens the connection with back stop 33. At other times, the spring of this traveling contact keeps the connection with back sto 33 closed as' shown in the drawings. Be ore the train reaches track contact 5,"the magnet 36 isenergized from generator 31 by the following circuit-from generator 31,

Front contact 41 is con- The spring 42 holds its armaside.

wire 32, back stop 33,'contact 34, wire 35, magnet 36, wires 37 and 38, back to generator. v

The operation of the system is as follows Before the train reaches the track contacts 5 and 6, the local train circuit through magnet 36, just above traced, energizes the ma net and closes the circuit through lamp 43, w ich is a white lamp and ives asafety indication. When the train reae es track contacts 5 and 6, traveling contact 51 makes connection with track contact 6 thereby connecting generator 31 with the supply circuit, as heretofore traced. This circuit operates transformer 8 and energizes track magnet 17 thereby cutting out lamp 23 and cutting in lamp, 29 which thereupon lights up to show safety. At the same time, traveling contact 34 makes connection with track contact 5 and breaks at back stop 33 the local train circuit through ma net 36 but connects this magnet by means 0 co-operating contacts 34 and 5 and by means of contact 53 with the track circuit so that this magnet 36 is immediately energized from current in the track circuit thereby causing safety lamp 43 to continue lighted. If, at this time, a train is occupying the block, the train magnet 17 will be deenergized thereby causing track lamp 23 to li ht up to indicate danger.: The presence of the train in the block also prevents magnet 36 from beingenergized by the track circuit so that armature 40 cuts out safety lam 43 and cuts in danger lamp 48 causing the fatter to light up.

The resistances of the various lampsand magnets, especiallythose on the train can be adjustedin a way so as to secure the best'results.

In Fig. 2 are shown three track si nals, each consisting of a danger and safety amp. I The danger lamps 23 are connected in multiple by wires 22 and 24 to back contact 21 on a one side and to wire 25 on the other side. The safety lamps 29 are connected in multiple by wires 28 and 30 .to front contact 27 on one side and to Wire 25 on the other side. Each pair of danger and safety'lamps 23 and 29 constitutes a signal. In Fig. 2, 61 is a magnet carried on the train and connected. by wires 62 and 63, respectively, to contact 41 on one'side and to wire 37 on the other The armature 60 of this magnet is connected by link 59 to lever 57fulcrumed at 58 and operating a valve 55 in lluidpressure pipe 56. This fluid pressure pipe may control or operate a whistle, or other signal, or serve to apply-the brakes. Magnet 611's energized concurrently with safety lamp 43.

When magnet 36 is denergized and lamp 48 lights up toindicate danger, magnet 61- is deenergized, its armature is retracted by spring 64 thereby operating valve 55 to apply the brakes or blow the whistle, as deslred.

In Fig. 3 is shown a diagram of a rotary transformer or motor dynamo 8.

8 shownin Figs. 1 and 2, in which case wires 1-0, 15, 12 and 14 will be connected in the track circuit and in the supply circuit in sub stantially the same way as shown in Figs. 1 and 2.
